Conditional Entities

The Conditional Entity Type makes it possible to create entities that provide a value depending on whether a condition is true or false. It can be used for example to have a part of a document vary depending on the browser or domain of a visitor.

This entity type is integrated in Interaction 1.2 and later.

A conditional entity is created using New from the Entities dialog. The topmost part of the dialog is a condition. When the entity value is evaluated, Interaction will get a value for the named entity and check whether it contains the text that are typed into the field. If this is the case, the value of entity will be the first of the large fields. If it is false, the second field will be the value of the entity. All fields can contain references to other entities to give you a high level of flexibility.

Conditional entities can be used instead of more primitive ways to create conditional content such as show/hide tags or SSI's. It can also be combined with SGML Marked Sections if you want to use markup to hide parts of the content of a document depending on a condition.
